Abstract

Colloidal semiconductor nanomaterials form a class of materials that offers the possibility for studying the physics of highly confined electrons and open opportunities for applications on several areas. However, a number of important electronic phenomena occur on a ultra-short timescale, from hundreds of femtosecond to some picoseconds and their spectral behavior are hidden underneath the broad absorption and emission bands, due to the finite size distribution. Here we propose to use a multidimentional coherent spectroscopy technique, which allows for temporal and spectral resolution high enough to investigate processes such as electron-electron and electron-phonon interaction and multi-exciton dynamics in those materials. We will combine Prof. Cundiffs group's, which have developed this technique, large experience on coherent multidimentional spectroscopy with Prof. Padilha's group's experience on ultrafast spectroscopy of nanomaterials, to address fundamental questions concerning the electronic dynamics in novel these nanoparticles, whose band structure has been engineered to try to control the interactions described above. Finally, this project will help on the development of this technique at UNICAMP, which will be the first time this method is built in Latin America. (AU)
